The Yuman Desert fringe-toed lizard (Uma cowlesi) is a species of phrynosomatid lizard endemic to northwestern Mexico, although a hybrid population of it and Uma notata ranges north to southwestern Arizona in the United States. [1]
This species has a confusing taxonomic history. Previously, it was referred to as Uma rufopunctata (described by Edward Drinker Cope in 1895), and was defined as ranging from the vicinity of Yuma, Arizona south to the Gran Desierto de Altar, and southeast from here through Puerto Penasco south to the Tepoca Bay. In 1941, Heifetz described Uma notata cowlesi as a new subspecies of the Colorado Desert fringe-toed lizard (Uma notata), and synonymized Uma rufopunctata with Uma notata; however, the name Uma rufopunctata was kept for this species by later sources. [1] [2] [3] Finally in 2016, Gottscho et al. found Cope's rufopunctata to in fact represent a hybrid population between Uma notata and Uma cowlesi, and thus only recognized notata and cowlesi as distinct species. [4]
This species is restricted to the Yuma Desert, where it is found in a small coastal portion of the Mexican state of Sonora. The hybrid between it and U. notata ("Uma rufopunctata") ranges further north through Sonora into southern Arizona. [4] The Reptile Database erroneously lists it as endemic to Arizona. [1]
The specific name, cowlesi, is in honor of American herpetologist Raymond Bridgman Cowles. [3]
The Sonoran Desert is a hot desert in North America and ecoregion that covers the northwestern Mexican states of Sonora, Baja California, and Baja California Sur, as well as part of the southwestern United States. It is the hottest desert in both Mexico and the United States. It has an area of 260,000 square kilometers (100,000 sq mi).
The Crotaphytidae, or collared lizards, are a family of desert-dwelling reptiles native to the Southwestern United States and northern Mexico. Alternatively they are recognized as a subfamily, Crotaphytinae, within the clade Pleurodonta. They are very fast-moving animals, with long limbs and tails; some species are capable of achieving bipedal running at top speed. This species is carnivorous, feeding mainly on insects and smaller lizards. The two genera contain 12 species.
The greater earless lizard is the only species in the monotypic genus Cophosaurus. It is closely related to the smaller, lesser earless lizards and other species in the genus Holbrookia, and in fact was placed in that genus and referred to Holbrookia texana from 1852 into the 1970s. Earless lizards lack external ear openings, an adaptation to burrowing in the sand, as are the recessed lower jaw and flared upper labial scales. Greater earless lizards are sexually dimorphic, males grow larger and are more colorful than females, exhibiting pink and green colors that are particularly bright in the breeding season. Two bold black bars mark the lateral region of males but are greatly reduced and vague, or occasionally entirely absent in females.
Spiny lizards is a common name for the genus Sceloporus in the family Phrynosomatidae. The genus is endemic to North America, with various species ranging from New York, to Washington, and one occurring as far south as northern Panama. The greatest diversity is found in Mexico. This genus includes some of the most commonly seen lizards in the United States. Other common names for lizards in this genus include fence lizards, scaly lizards, bunchgrass lizards, and swifts.
Fringe-toed lizards are lizards of the genus Uma in the family Phrynosomatidae, native to deserts of North America. They are adapted for life in sandy deserts with fringe-like scales on their hind toes hence their common name.
The Texas horned lizard is one of about 21 North American species of spikey-bodied reptiles called horned lizards, all belonging the genus Phrynosoma. It occurs in south-central regions of the US and northeastern Mexico, as well as several isolated introduced records and populations from Southern United States. Though some populations are stable, severe population declines have occurred in many areas of Texas and Oklahoma. The Texas spiny lizard may be confused for a Texas horned lizard due to its appearance and overlapping habitat.
The desert horned lizard is a species of phrynosomatid lizard native to western North America. They are often referred to as "horny toads", although they are not toads, but lizards.
The Coachella Valley fringe-toed lizard is a species of phrynosomatid lizard.
Aspidoscelis is a genus of whiptail lizards in the family Teiidae.
The coast horned lizard is a species of phrynosomatid lizard endemic to Baja California Sur in Mexico. As a defense the lizard can shoot high pressure streams of blood out of its eyes if threatened.
Sceloporus magister, also known as the desert spiny lizard, is a lizard species of the family Phrynosomatidae, native to the Chihuahuan Desert and Sonoran Desert of North America.
The flat-tail horned lizard is a species of lizard in the family Phrynosomatidae. A species of reptile, it is endemic to the Sonoran desert of the southwestern United States and northwestern Mexico. Its multiple adaptations for camouflage help to minimize its shadow. The species is threatened, with a restricted range under pressure from human activities such as agriculture and development, and is specially protected in the United States.
The Mojave fringe-toed lizard is a species of medium-sized, white or grayish, black-spotted diurnal lizard in the family Phrynosomatidae. It is adapted to arid climates and is most commonly found in sand dunes within the Mojave Desert. Fringe-toed lizards are characterized by their fringed scales on their hind toes which make locomotion in loose sand possible.
Raymond Bridgman Cowles was a herpetologist and professor at University of California, Los Angeles. Born in the British Colony of Natal to American missionary parents, he emigrated to the United States in the early 1900s. He attended Pomona College as an undergrad and earned his PhD at Cornell University under Albert Hazen Wright. He is known for his research on desert ecology and reptile thermoregulation, as well as his popular books on environmental conservation. Cowles died of a heart attack in 1975 at the age of 79. An obituary called him one of America's first ecologists and conservationists.
Alto Golfo de California Biosphere Reserve is a UNESCO Biosphere Reserve located in the state of Sonora in extreme northwestern Mexico. Thee 1,652,110 hectares (6,378.8 sq mi) reserve comprises the El Pinacate y Gran Desierto reserve and the Bahia Adair on the Gulf of California border. Geological volcanic formations with craters, dunes, oasis and beaches, and the diversity of plant associations determine its special landscape. The reserve was established in 1993 by the President of Mexico as Reserva de la Biosfera del Alto Golfo de California y Delta del Río Colorado and extended in 1995.
Acanthodactylus schmidti, also known commonly as Schmidt's fringe-fingered lizard or Schmidt's fringe-toed lizard, is a species of lizard in the family Lacertidae. The species is endemic to Western Asia.
The Colorado Desert fringe-toed lizard is a species of medium-sized, diurnal lizard in the family Phrynosomatidae. It is adapted to arid climates and is most commonly found in sand dunes within the Colorado Desert of the United States and Mexico.
The Mohawk Dunes fringe-toed lizard is a species of phrynosomatid lizard endemic to the U.S. state of Arizona. Its name is a reference to American actress Uma Thurman, as both a pun on the genus name Uma as well as a tribute to the actress for her conservation advocacy.
